Rump kernels enable you to build the software stack you need
without forcing you to reinvent the wheels. The key observation is
that a software stack needs driver-like components which are conventionally
tightly-knit into operating systems — even if you do not desire the
limitations and infrastructure overhead of a given OS, you do need drivers.

We solve the problem by providing free, reusable, componentized, kernel
quality drivers such as file systems, POSIX system calls,
PCI device drivers and TCP/IP and SCSI protocol stacks.
For examples of what you can achieve with rump kernels, see the
repositories
we provide. There is also a wiki page for
3rd
party projects using rump kernels.
